Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488678, here are decompositions:

37 + 488641 = 488678
61 + 488617 = 488678
67 + 488611 = 488678
139 + 488539 = 488678
271 + 488407 = 488678
277 + 488401 = 488678
331 + 488347 = 488678
349 + 488329 = 488678

Showing the first eight; more decompositions exist.
